The Global 2000-2020 Land Cover and Land Use Change Dataset Derived From the Landsat Archive: First Results
Year: 2022
Type: article
Abstract: Recent advances in Landsat archive data processing and characterization enhanced our capacity to map land cover and land use globally with higher precision, temporal frequency, and thematic detail. Here, we present the first results from a project aimed at annual multidecadal land monitoring providing critical information for tracking global progress towards sustainable development. The global 30-m spatial resolution dataset quantifies changes in forest extent and height, cropland, built-up lands, surface water, and perennial snow and ice extent from the year 2000 to 2020. Landsat Analysis Ready Data served as an input for land cover and use mapping. Each thematic product was independently derived using locally and regionally calibrated machine learning tools. Thematic maps validation using a statistical sample of reference data confirmed their high accuracy (user’s and producer’s accuracies above 85% for all land cover and land use themes, except for built-up lands). Our results revealed dramatic changes in global land cover and land use over the past 20 years. The bitemporal dataset is publicly available and serves as a first input for the global land monitoring system.

Awards: G1618731163, G2078476648, THIS PROPOSED FOOD SECURITY AND AGRICULTURE CONSORTIUM (FSAC) WILL ADDRESS VARIOUS ASPECTS OF THE APPLICATION OF EARTH OBSERVATIONS (EO) TO DOMESTIC AND GLOBAL AGRICULTURE AND FOOD SECURITY THROUGH AN UNPRECEDENTED GROUP OF RESEARCH AND OPERATIONAL PARTNERS. WE HAVE ASSEMBLED A CONSORTIUM OF PRINCIPALS DRAWN FROM LEADING ORGANIZATIONS IN THE U.S. AND AROUND THE WORLD THAT USE EO AND DERIVED INFORMATION TO ADVANCE AGRICULTURE AND FOOD SECURITY. THE PROPOSED FSAC ANCHORS A BROAD NETWORK OF PARTNERS DRAWN FROM UNIVERSITIES GOVERNMENT AGENCIES AND RESEARCH ORGANIZATIONS NGOS INTERNATIONAL ORGANIZATIONS AND THE PRIVATE SECTOR REPRESENTING END USERS INFORMATION AND SERVICE PROVIDERS AND APPLICATIONS RESEARCHERS. FSAC PARTNERS LEAD THE WORLD IN ENGAGING END USERS IN USING EO-DERIVED INFORMATION FOR AGRICULTURE. THE FSAC EXPANDS ON EXISTING AND PAST NASA INVESTMENTS AND IS SPECIFICALLY DESIGNED TO AMPLIFY THE BENEFITS BROADLY THROUGH PUBLIC AND PRIVATE SECTORS IN THE US AND INTERNATIONALLY. LEVERAGING OUR CURRENT AND PAST WORK TO BUILD THE GEO G20 GLOBAL AGRICULTURAL MONITORING (GEOGLAM) INITIATIVE THE CURRENT PROPOSAL IS ESSENTIAL TO THE CONTINUED IMPLEMENTATION AND DEVELOPMENT OF GEOGLAM WHICH HAS ACHIEVED UNPRECEDENTED SUCCESS IN ENGAGING END-USERS INVOLVED WITH CROP PRODUCTION MONITORING AND FORECASTING. THROUGH THIS PROPOSAL THE CROP MONITORS LED BY UMD WILL CONTINUE TO DELIVER EO-DERIVED INFORMATION TO THE AGRICULTURAL MARKET INFORMATION SYSTEM (AMIS) AN INTERNATIONAL BODY OF CHIEF ECONOMISTS FROM MAJOR CROP EXPORT COUNTRIES AND PROVIDE A MONTHLY BULLETIN OF CROP CONDITIONS FOR FOOD INSECURE COUNTRIES WITH AN EXPANDING GROUP OF INTERNATIONAL AND NATIONAL FOOD SECURITY ORGANIZATIONS. THE FSAC END USER ENGAGEMENT WILL BE BROAD - ADDRESSING NOT ONLY INTERNATIONAL CROP PRODUCTION FORECASTS MARKETS AND TRADE ALONGSIDE REGIONAL/NATIONAL FOOD SECURITY EARLY WARNING DISASTER RESPONSE AND POLICY - BUT ALSO DOMESTIC COMMERCIAL AGRICULTURE AND FARM MANAGEMENT AND SMALLHOLDER FARM MANAGEMENT RESILIENCE AND MICRO-INSURANCE. IT WILL INCLUDE STRATEGIC SYSTEMATIZED ENGAGEMENT OF NON-TRADITIONAL USERS OF NASA DATA (INSURANCE INDUSTRY HUMANITARIAN ORGANIZATIONS AND INTELLIGENCE). THE FSAC MEMBERS WERE SELECTED STRATEGICALLY FOR THEIR EXPERTISE AND RELATIONSHIPS WITH A BROAD RANGE OF USER-GROUPS. OUR APPLICATIONS R&D WILL FOCUS ON CROP CONDITION MONITORING AND RISK ASSESSMENT CROPLAND CROP TYPE AND AREA MAPPING CROP YIELD AND PRODUCTION MODELING AND FORECASTING AND LINKING EO PRODUCTS TO SOCIO-ECONOMIC DATA TO ADDRESS FOOD SECURITY QUESTIONS. THE RESULTING SUITE OF INNOVATIVE PRODUCTS AND SERVICES WILL COMBINE EO PRODUCTS FROM DIFFERENT SENSORS WITH METEOROLOGICAL GROUND AND SURVEY DATA. OTHER MAJOR WORK ELEMENTS WILL INCLUDE: THE ECONOMIC AND SOCIAL VALUATION OF THE BENEFITS OF EO THROUGH ECONOMIC ANALYSIS OF EO FOR PRODUCTION FORECASTING AND REPRESENTATIVE END USER CASE STUDIES; LINKAGE TO NEW NASA SENSORS ENHANCING THE EARLY ADOPTERS PROGRAM; DEVELOPMENT OF AN FSAC PORTAL FOR INFORMATION COLLECTION DISSEMINATION AND INNOVATIVE COMBINATION; AND A PROFESSIONAL COMMUNICATIONS INITIATIVE GIVING BROAD OUTREACH FOR THE PROGRAM. THE DOMESTIC AGRICULTURE COMPONENT OF THE PROPOSAL WILL TEST NEW EO-BASED APPLICATIONS TO IMPROVE FARM MANAGEMENT AND HELP USDA NASS IMPROVE THE RELIABILITY OF ITS US STATISTICS (AREA/YIELD). FSAC WILL HOLD A SERIES OF THEMATIC COMMUNITY WORKSHOPS IN THE US ESTABLISHING A US GEOGLAM COMMUNITY OF PRACTICE (COP) TO COMPLEMENT THE INTERNATIONAL COP. THESE ACTIVITIES TOGETHER WILL DELIVER NASA AN OUTSTANDING COORDINATED AND WELL-BALANCED PROGRAM APPLYING EO TO FOOD SECURITY AND AGRICULTURE WITH STRONG CONNECTIONS TO RELEVANT NASA PROGRAMS SCIENCE TEAMS AND NEW MISSIONS. A GOAL OF THE FSAC IN ADDITION TO RESPONDING TO THE RFP IS TO EXPAND ITS ACTIVITIES PARTNERSHIPS AND COLLABORATIONS WITH NON-NASA FUNDING SUSTAINING THE CONSORTIUM AND ITS FUNCTIONS BEYOND THE 5-YEAR FUNDING PERIOD., G5488629387
